The habituation of bean cells to quinclorac did not rely on cell wall modifications, contrary to what it was previously observed for the well-known cellulose biosynthesis inhibitors dichlobenil or isoxaben. The aim of the present study was to investigate whether or not the bean cells habituation to quinclorac is related to an enhancement of antioxidant activities involved in the scavenging capacity of reactive oxygen species. Treating non-habituated bean calluses with 10 μM quinclorac reduced the relative growth rate and induced a two-fold increase in lipid peroxidation. However, the exposition of quinclorac-habituated cells to a concentration of quinclorac up to 30 μM neither affected their growth rate nor increased their lipid peroxidation levels. Quinclorac-habituated calluses had significantly higher constitutive levels of three antioxidant activities (class-III peroxidase, glutathione reductase, and superoxide dismutase) than those observed in non-habituated calluses, and the treatment of habituated calluses with 30 μM quinclorac significantly increased the level of class III-peroxidase and superoxide dismutase. The results reported here indicate that the process of habituation to quinclorac in bean callus-cultured cells is related, at least partially, to the development of a stable antioxidant capacity that enables them to cope with the oxidative stress caused by quinclorac. Class-III peroxidase and superoxide dismutase activities could play a major role in the quinclorac-habituation. Changes in the antioxidant status of bean cells were stable, since the increase in the antioxidant activities were maintained in quinclorac-dehabituated cells.

“…The increase on the ACC levels results in the action of ACO, leading to an accumulation of ethylene and cyanate (Figure 2) on the tissues (Sunohara et al, 2011). A hypothesis is that grass species sensitive to quinclorac do not have the ability to detoxify cyanate quickly, accumulating the product, which generates phytotoxic effects (Grossmann & Kwiatkowski, 2000;Abdallah et al, 2006;Grossmann, 2010).…”

“…D. adscendents plants treated with quinclorac synthesized 3.4 times more antioxidant enzyme (superoxide anion scavenging activity, SOSA) than untreated plants, indicating that this process may be involved in the action of the herbicide (Sunohara et al, 2011). Eleusine indica plants showed high activity on the enzymatic protection system to eliminate ROS, suggesting that this process may be responsible for the tolerance to herbicides that induce the overproduction of ROS, such as Integrative theory of the mode of action of quinclorac: literature review quinclorac (Sunohara et al, 2011 (Sunohara & Matsumoto, 2004).…”

“…On dicotyledons, it is likely that quinclorac shows auxinic action, acting on the biosynthesis of ethylene, ABA and ROS (Hansen & Grossmann, 2000;van Eerd et al, 2005;Grossmann, 2010). On monocot plants, there are some controversies on its effect, and there is evidence of inhibition of the biosynthesis of the cellular wall (Koo et al, 1996;Koo et al, 1997), as well as ethylene and cyanate biosynthesis (McMahon et al, 2000;Abdallah et al, 2006;Grossmann, 2010), or even the overproduction of ROS (Sunohara & Matsumoto, 2008;Sunohara et al, 2011).…”

“…The third hypothesis that would explain the quinclorac activity is related to its ability to induce the production of ROS, thus, suggesting that they would be responsible for the phytotoxic effects on susceptible grass plants (Sunohara et al, 2011). The accumulation of ROS inhibits the electron transportat during photosynthesis, promotes damages to the chlorophyll, damages proteins, membrane lipids and nucleic acids (Bowler et al, 1992;Sunohara & Matsumoto, 2004).…”

-Quinclorac is a systemic herbicide absorbed by germinating seeds, roots and leaves of seedlings. It is a selective compound for crops such as rice, canola, barley, corn, sorghum, and pasture. Quinclorac can be used to control various monocots and dicotyledonous weed species. The biochemical function of this herbicide in the plant has intrigued scientists for nearly four decades. The objectives of this review are to present evidence of three hypotheses on the biochemical functioning of quinclorac and to propose an integrative mode of action. The first theory on the mode of action of quinclorac is supported by evidence of inhibition of incorporation of C 14 -glucose into cellulose and hemicellulose, thus, affecting the cell wall synthesis. The second hypothesis suggests that quinclorac acts as an auxin in broadleaved weed species. In grass species, however, this herbicide appears to stimulate the activity of the 1-aminocyclopropane-1-carboxylate synthase enzyme and, subsequently, to increase the ethylene production; also, it seems to increase the cyanide acid content to phytotoxic levels. A third hypothesis to explain the harmful effect in some plant species is the formation of reactive oxygen species (ROS). Apparently, these processes are not mutually exclusive; therefore, an integrative theory for the action of quinclorac is suggested. It is theorized that the aforementioned biochemical activities are interconnected and can be the phytotoxic backbone to explain the herbicidal effect depending on the plant species and the plant growth stage, among other factors.Keywords: cellulose biosynthesis-inhibitor, cyanide, auxinic herbicide, reactive oxygen species.

BACKGROUND: Barnyardgrass (Echinochloa spp.) is a global weed in rice fields. Quinclorac is commonly used to control barnyardgrass. However, due to persistent use, quinclorac resistance has evolved. We obtained quinclorac-susceptible (QS) and-resistant (QR1, QR2) lines from the progeny of a single resistant E. crus-pavonis for a resistance mechanism study. RESULTS: Line QR1 exhibited resistance to high quinclorac rates (up to 6400 g ha −1), whereas line QR2 exhibited a resistance/ susceptibility segregation ratio of 3:1 at the field or lower rates (400, 100 g ha −1). Intriguingly, a lower level of 14 C-quinclorac metabolism and hence a higher level of 14 C-quinclorac translocation was observed in QR1 than QS plants. The basal expression levels of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (ACS) and ACC oxidase 2 (ACO2) genes did not differ significantly between the QR1 and QS lines. However, more expression of ACS and ACO genes was induced by quinclorac treatment in QS than in QR1. Basal levels of ⊎-cyanoalanine synthase (⊎-CAS) gene expression were similar in QS and QR1 plants, but a greater level of down-regulation was detected in QS than in QR1 plants after quinclorac treatment. CONCLUSION: These results indicate QR plants are less responsive to quinclorac than QS plants in terms of up-regulating quinclorac metabolism and ethylene synthesis. Resistance in this E. crus-pavonis line is likely controlled by a single major gene, involving possibly an alteration in auxin signal perception/transduction to the ethylene biosynthesis pathway. The ⊎-CAS is unlikely to play a major role in quinclorac resistance in this particular population.
